that's where i'm at. I installed an EDC earlier this season, and on most rides i don't need to carry a pack. only thing in my pocket is car ket, photo id, and maybe chapstick.I've been thinking about moving away from them as well, using a strap for tube and doing the oneup pump/tool watercollte cage attachment. The only place I think I'd really need a pack then is for backcountry rides over 20 miles when I need more food/hydration. I do wear my pack with button down shirts with no issues - did you feel like the shirt rides up too much?
